CONT

Preharvest sprouting (PHS) is a phenomenon whereby seeds germinate while still attached to the mother plant. The occurrence of PHS in hexaploid wheat (Triticum aestivum L.) can drastically lower grain quality resulting in reduced prices for farmers. Wheat is susceptible to PHS anytime cool wet weather persists near harvest maturity, making it a problem in nearly all wheat growing regions worldwide. The main factor contributing to PHS susceptibility is the low level of seed dormancy encountered in modern cultivated varieties.

OBS

Of cereals in the field.

CONT

La germination sur pied. Des conditions humides, juste avant la récolte du blé, peuvent faire démarrer la germination des graines alors qu'elles se trouvent encore dans les épis. Des enzymes, en particulier des amylases, commencent à transformer l'amidon en sucre, nécessaire au développement de l'embryon. La germination sur pied peut avoir des effets néfastes sur la panification, et même un lot apparemment non germé peut être affecté.

OBS

Des céréales avant la récolte.
